The Basic, Short-distance Ferry-RORO is one of the most ubiquitous ship types in the Philippines. Where before Motor Boats (MBs), the old designation and Motor Bancas (MBcas) use to connect our nearer islands, now it is this type that do that role, aside from the less-developed or small islands where vehicle and cargo traffic is not sufficient to sustain operations of steel-hulled ferries. In that case, therefore, it will still be the Motor Bancas that will do the connection as Motor Boats are already on the way out as short-distance route connections.
These small, simple ROROs are basically from sub-30 meters in length (in LBP or LR) to sub-40 meters with a beam of 7 to 10 meters, all rounded off, with a GT (Gross Tonnage) of generally less than 300 tons and an NT (Net Tonnage) of less than 200. The design consists of a car/cargo deck below and a single passenger deck above with the bridge generally located at the same upper level and in the forward (abaft) location. Commonly, there is only one, non-articulated cargo ramp located at the bow. Since they are short-distance ferries passenger accommodation will consist just of benches (the hallmark of a short-distance ferry) with the most basic amenities like TV sets for viewing, a snack bar which is locally called as canteen and maybe a videoke or some video games. A very few will have an air conditioned Tourist section. Passenger capacity of this type is usually between 200 and 300.
This type of ferry is typically equipped with just one marine engine with the output usually in the 600 to 1,000 horsepower range and the most common installed is the Daihatsu marine engine. The cruising speed is usually 11 knots at most with some older or underpowered ones barely making 9 knots. Most of this type will carry only six long trucks but more if the the vehicles are sedans or pick-up trucks. Motorcycles will be slotted where there is some free space and this will usually be in the bow near the ramp. In loading the biggest and heaviest is usually loaded first in some sort of a choreographed “dance”. Putting a heavy truck at the stern without a counterbalance at the bow can capsize this type stern-first. Cargo or load masters sequence this “dance” unless most of the vehicles to be loaded are small so it will just be a matter of balancing it starboard and port.
Most of this ferry type in the Philippines came from Japan. They will not look much different in design because many of them are actually sister ships which means they share the same hull-form. This is so because they were based on one of the designs commissioned by the Ministry of Trade and Industry (MITI) of Japan. That was meant to simplify research and development to lessen cost and help the small ship builders of Japan. In Japan this type is usually limited to secluded seas and bays but in the Philippines they are used even in seas with reputation for high swells and strong winds.

The routes of the Basic, Short-distance Ferry-RORO are usually from 2 to 40 nautical miles distance with transit times of from a quarter of an hour to four hours or so if the route is a bit long and the ferry is really slow (and in that case a Large Motor Banca will overtake the basic, short-distance RORO). As of this writing (January 2015) there are more than 45 routes served in the country by the Basic, Short-distance Ferry-ROROs but that total includes those served by Ropax and Hybrid LCTs and by the bigger short-distance ROROs.
Most of our Basic, Short-distance Ferry-ROROs are already old with many built in the 1970s. However, they are still reliable since Daihatsu marine engine parts are easy to source and they are easy to maintain. Should an engine be at the end of its economic life, many replacement engines are easily available in the surplus market. That is also true for the other machinery and bridge equipment. With a robust design and many replacement parts available this type is not anywhere near retirement. If there is a threat to this type it comes from the arrival of bigger short-distance ferriy ROROs which are newer and faster. This can load more and so when it is peak season or there are a lot of buses on board passengers need not use the stairs or deck for sitting. Many of these bigger short-distance ROROs have airconditioned accommodations and they roll less in heavy seas.
